A new RI-URBANS publication led by Karine Sartelet  quantifies intra-urban air pollution variability across five European cities (Paris, Athens, Birmingham, Rotterdam, and Bucharest) —at a resolution finer than 100 meters. Using advanced modeling techniques, the study compares both regulated (NO₂, PM₂.₅) and emerging pollutants (black carbon, ultrafine particles), quantifying their temporal and spatial variabilities.

These findings highlight the importance of fine-scale mapping to better estimate population exposure and inform public health strategies. The study also offers methodological guidance to improve urban air quality models in line with upcoming EU Air Quality Directive updates.
